# Finding the estimation of the total cost

Note: If the paise is more than 50 or equal to 50 add 1 to the previous digit, if it is less than 50 keep the previous digit as it is.

Finding the estimation of the total cost

Tharun went to footwear shop with his father. A pair of footwear cost  99.50 in the price tag.

Note: If the paise is more than 50 or equal to 50 add 1 to the previous digit, if it is less than 50 keep the previous digit as it is.

Tharun : Appa, what is the cost of the footwear?

Appa :  100

Tharun : Appa, the price tag shows  99.50 but you said  100.

Appa : Yes tharun. The amount  99.50 is difficult to tell. So I rounded off to  100.

Tharun : Appa, why don’t you say  99 instead of  100?

Appa : Yes, here the amount is  99.50. If the amount is more than or equal to 50 paise, round to the nearest value.

Tharun : Appa, Suppose if the amount is less than 50 paise, then keep the value as it is leaving the 50 paise?

Appa : Yes Tharun, you are correct. (They bought, footwear and went happily)

To measure the money accurately, we can use the approximation

The approximate value of  1 is the whole number of before or after.

Let us try
